This Flip Array is the only board with the unique feature of both 1-120 (red/black) and 0-119 (blue/red) on one product. Simply turn the unit around to swap between 1 to 120 and 0 to 119. There are no pieces to lose. Numbers reset at the flick of a wrist. Children often have difficulties in counting past 100, or understanding that there are numbers lower than 1. This flip array board tackles both of these issues with one resource! The board measures a large 65 x 55cm. Great for classroom demonstrations! Ideal for creating number sense, number patterns, addition, subtraction, counting, odd and even and much more!
